Spookey Posted February 17, 2004 Posted February 17, 2004 Dear All, I would love to hear your opinions regarding prefered breaking materials! How much harder is industrial yellow pine ( from the local home improvement store) versus the white pine most often used for breaking...does anyone have a density comparison between the two types! Hear is one specific question...at 1x12x12 (regular breaking size) 1 yellow pine board = (?) # of white pine boards? Looking foreward you guys input! TAEKWON!

Akima Posted February 17, 2004 Posted February 17, 2004 Spooky, I have no idea, very time I see people do breaking they go to Home depot. I really can't imagine there would be much difference, unless the HD pine is chemicaly treated
Toast Posted February 17, 2004 Posted February 17, 2004 My school uses wood cut for breaking from TK Corea in NJ...and yes its spelled like that...

MichiganTKD Posted February 18, 2004 Posted February 18, 2004 I generally use standard 1x12x12 spruce boards for regular beaks. For special breaks, such as high or long jumping, I will have them cut a little thinner. For patio blocks, I just go to the home improvement stores and get 2" blocks. Nothing fancy. My opinion-Welcome to it.
Bretty101 Posted February 18, 2004 Posted February 18, 2004 ?? We usually just get 10x10x1 pine when we do demos. We just ask for pine? don't know what we get. The man that works at the depot always laughs when we tell him what we're using it for. He says, "I bet you don't try and break it across the grain!! now that would be impressive!" One year we had a stack of wood, where it was left in the rain the top board got really wet. It must have been 3 times harder to break then all the others! Bretty
Darth Paul Posted February 22, 2004 Posted February 22, 2004 Anyone ever use rebreakable boards for practice? They're not as much fun but they force you to be accurate. If you don't hit them dead center they're probably not going to break-which makes a huge difference if you are breaking with a punch or a ridgehand strike.
The Saint Posted March 11, 2004 Posted March 11, 2004 Here's the density of Pine woods. Pine ( Oregon ) 530 kg/cu.m Pine ( Parana ) 560 kg/cu.m Pine ( Canadian ) 350 - 560 kg/cu.m Pine ( Red ) 370 - 660 kg/cu.m conversion factor from english to metric: 1 lb/ cu. ft =16.02 kg/cu. m The reason white pine is used is because it is less dense than yellow and can be broke easier. It is also a little cheaper when it comes to buying it depending on where you live. To buy really expensive wood and break it, is kinda silly and not economical. The dryness of the wood is also a fact to take into consideration. The more wet a wood is the more dense it will be. (harder to break). Another factor to look at when answering this question is what region the wood came from, different regions have differnt growing conditions. You could have the exact same breed of tree and the density of the wood be different because of growing conditions of where the wood came from. If you want to break yellow wood from the local hardware store, fill you boots. White pine is cheaper and more common in most places in North America though.
